But she stressed the oversight was a technicality and that none of the "defective" eight trustees had been acting illegally while serving on the council.
Neither would any decisions be invalidated, said Ms Prytherch.
She told members: "It is important to note that the eight trustees.... were elected by the membership and no member was disadvantaged by their election.
"The society's solicitors have confirmed these are defective appointments and not illegal.
"The omission of a seconding on the nomination form is a technicality that needs to be addressed but does not invalidate the actions of these trustees as directors."
